Description
Technical field
The invention belongs to illuminate and optical material technical field, more particularly to a kind of optical material and a kind of light guide plate.
Background technology
Illumination is indispensable in human lives.Illumination for most cases is required for illumination light to have uniform
Spatial light intensity (or brightness) is distributed.However, almost now all of light source is shone with putting luminous (i.e. point light source) or line
What the mode of (i.e. linear light source) worked.For example, common fluorescent tube and cold cathode tube (CCFL) just belong to typical linear light
Source, traditional incandescent lamp are shone with a segment filament, and point light source can be regarded as outside certain distance.Most typical point light source is answered
This is the semiconductor light-emitting-diode (LED) of currently fast development.The size of single led tube core is very small, luminous zone
Domain also very little, is real point light source for illumination.To realize Uniform Illumination, it is necessary to send out point light source or linear light source
Light be transformed into face shine.Common method is exactly that the material with light scattering or light diffusion is added before light source, is realized
Above-mentioned transformation.Such as in illuminating indoors, various forms of lampshades are commonly used, purpose is exactly to send out light bulb or fluorescent tube
Light is transformed into face and shines, and generates spatial distribution and more uniformly illuminates, eliminates the feeling of dazzle, and human eye is made to feel soft comfortable.
Use LED in the illumination of luminescent device, light scattering or the effect of photodiffusion material then seem more important.
Oneself, which has, realizes that the method that light is spread includes:1) optics of rule or random distribution is produced on the surface of transparent material
Structure, such as lenticule, microprism.When light passes through these micro-structures, refraction, incident light are generated at the interface with air
The direction of propagation occur deviation, to generate photodiffusion effect.The characteristics of ~ beans method, is that light transmission rate is higher, but due to
The only refraction at interface, so light diffusion effect is not ideal enough.2) so-called light diffusing agent is added in transparent material, is made
Light scattering or photodiffusion material.Light diffusing agent is actually the particle with a certain size distribution, and material can be inorganic
Can also be organic.Common inorganic particulate have silica, oxidation cutting edge of a knife or a sword, ferrous oxide, oxidation mistake, aluminium oxide, vulcanize cutting edge of a knife or a sword,
Sulfuric acid dam and its mixture etc..Common organic granular includes styrenic polymer, acrylic polymer, silica a heatable brick bed
Type of Collective object etc..Light diffusing agent particle is added in transparent base by various modes, and obtained photodiffusion material is generally visual
For volume diffusing material, incident light can be in volume diffusing material by Multiple Scattering, reflection and refraction.Inorganic light diffusing agent particle one
As have irregular shape also opaque, they mainly scatter the effect of incident light.It is well known that the equal companion of light scattering process
As the transformation of different degrees of light absorption, therefore above-mentioned light is all to lose certain light energy as cost.Organic light
Diffusant particle can have regular shape (as spherical or close to spherical shape), also transparent in various degree.In this case, light
Diffusion is mainly realized in a manner of reflecting and reflecting.
The important technological parameters for characterizing light scattering or photodiffusion material performance include light transmittance and mist degree.Light transmittance indicates light
Diffusion material is to the overall utilization of incident light, and mist degree then indicates that incident light deviates the degree of former incident direction, therefore can use
To characterize the diffusion that photodiffusion material introduces incident light.For the photodiffusion material based on KPT Scatter, mist degree
Increase must cause the reduction of light transmittance.In fact, its light transmittance of the lampshade used in people's daily life is not very
It is high, that is to say, that there is quite a few light energy to be lost.Therefore, light diffusion materials of the exploitation with high transparency and haze
Material is particularly significant for efficiently using the luminous energy of light source.Other than general lighting, high-efficiency photodiffusion material is for display technology
Development it is also most important.At present LCD displays oneself obtained in Computer display, domestic television set and large screen display
Extensive use.LCD needs the backlight lighting device of uniform-illumination in showing, make the backlight of light source in particular by LED devices
Illuminating device.As previously mentioned, LED is typical point light source, to convert thereof into the area source of uniform-illumination could be used for LCD
Backlight, and the photodiffusion material with haze and high transparency is the critical material for realizing above-mentioned conversion.
Light guide plate hardness prepared by current photodiffusion material mostly is high, but toughness is inadequate, is using and is holding in transportational process
It is broken, it wastes resource and improves cost.
